Abstract
The utility model discloses a power surge protector, comprising a cabinet, two electrode fixing plates symmetrically disposed in the middle of the cabinet, a graphite protection assembly fixed between the two electrode fixing plates, a wiring terminal electrically connected with two sides of the graphite protection assembly, and an indicating circuit disposed in the cabinet and electrically connected with the graphite protection assembly. The graphite protection assembly comprises at least two graphite flakes arranged between the two electrode fixing plates parallelly at interval, an insulating sheet disposed between the two adjacent graphite flakes, and insulating positioning plates fixed on the graphite flakes and two ends of the insulating sheet. Through connecting multistage graphite with the insulating sheets, at the moment when overcurrent occurs in a working circuit, or during a bit of time of continuous overcurrent, the graphite protection assembly discharges the overcurrent in the circuit by using characteristics of the assembly, so that current transmitted in the circuit is normal, thereby ensuring normal operation of devices. The processing technology of the graphite protection assembly is simple, and product consistency can be preferably ensured.
